IMPROVED SEWED SHOE.

Specification forming part of Letters Patent No. 50,462, dated October 17, 1865.

To all whom it may concern.-

Be it known that I, HENRY DUNHAM, Jr.,

' of Abingdon, countyof Plymouth, and State of thestitches forming this union shall -pass through the inner edge of the uppers, .but not pass through the bottom ofthe sole,an d therefore shall be invisible from Vthe other side, or,

l if the shoe is turned, from the outside.

In tliedrawings,Figurelrepresents a trans verse section through a shoe and last, the former being afterward turned when the latter is removed. Fig. 2 represents a transverse section Athrough a vshoe and last, showing the inner sole, the `vamp, and the weltjoined at one operation.

The process of preparing-tliat is, lasting, &c.-a shoe preparatory to sewing it is too well known by those skilled'in the art to need any detailed description. The upper and sole, however, are to be properl y secured to the last, so as to avoid any displacement or disturbance of parts during the operation and permit of an uninterrupted one, if possible.

former; C,t hela'.st; D, the welt. E represents a. curved hooked needle, and F the awl'attached to two curved arms operatedby my machine patented September 9, 1862, reissued December 16, 1862, and since undergoing further improvements.

. Theoperationofproducingstitchesby means of a waxed thread, a'needle, and an awl, Ste., is. we ll known and needs no particular descrip tion, and the manner of operating the curved arms carrying the needle'and awl and of feeding the work will be found in the patent aboqe referred to.

The advantage gained by the process is that we do not sew entirely through the'lsole, but with the curved needle dip into it, coming out through the upper leather or vain p (which laps 4 over the edge ofthe sole) without having passed through the bottomo'f the sole. The needle makes a curved passage from `the surface of 'the sole at one point to the saine surface at another point, coming out through the edge of the vamp, which is lapped over the edge ofthe sole.` When the sewing is completed, ifa turned shoe., the last is .removed and the shoe turned, the outer edge of the sole properly trimmed, and sometimes an yinner sole inserted, none ot the stitches being visible from the outside,a-

desirable point particularly for thin-sotedior pump shoes, and more durable, not being eX- posed to wear.

If a welted shoe' be wanted, the shoe islasted on the right side, the inner sole, vamp, and welt sewed together in saine manner at one operation, and when this iscoinpleted another sole is attached in the-usual way, which is too well known to require description.

What, therefore, I claim :is-new, and desire to secure by Letters Patent of the United States, is`

As an article of manufacture, a sewed shoe with the vamp or upper and vsole united by machine by chain-stitches passing through the In the drawings referred to, A represents the l sole 5 B, the upper overlap ping the edge of the vamp and the inner Surface of the sole, not passing entirely through its bottom, the said stitching being on a tnrnedshoe on the inside and entirely concealed when the article is' n' ish'ed' and on awelted shoe being also concealed, being covered by. another sole.
